我在我的xamarin.forms项目中使用xam.plugin.pughnotification
我的主要活动
protected override void OnCreate(Bundle bundle)
{
TabLayoutResource = Resource.Layout.Tabbar;
ToolbarResource = Resource.Layout.Toolbar;
base.OnCreate(bundle);
global::Xamarin.Forms.Forms.Init(this, bundle);
//inicializa imageCircle
ImageCircleRenderer.Init();
//inicializa o mapa
global::Xamarin.FormsMaps.Init(this, bundle);
//shared Preferences
App.Init(new AndroidUserPreferences());
//Gerenciador de memória
CachedImageRenderer.Init();
try
{
AppContext = this.ApplicationContext;
CrossPushNotification.Initialize<CrossPushNotificationListener>("mysendernumbers");
StartPushService();
CrossPushNotification.Current.Register();
}
catch (Exception e)
{
var s = e.Message;
}
AndroidUserPreferences sharedPref = new AndroidUserPreferences();
//if ( sharedPref.GetString("token") == " ")
//{
GetTokenTask myTask = new GetTokenTask();
myTask.Execute(this);
//}
LoadApplication(new App());
}
public static void StartPushService()
{
AppContext.StartService(new Intent(AppContext, typeof(PushNotificationService)));
if (Android.OS.Build.VERSION.SdkInt >= Android.OS.BuildVersionCodes.Kitkat)
{
PendingIntent pintent = PendingIntent.GetService(AppContext, 0, new Intent(AppContext, typeof(PushNotificationService)), 0);
AlarmManager alarm = (AlarmManager)AppContext.GetSystemService(Context.AlarmService);
alarm.Cancel(pintent);
}
}
public static void StopPushService()
{
AppContext.StopService(new Intent(AppContext, typeof(PushNotificationService)));
if (Android.OS.Build.VERSION.SdkInt >= Android.OS.BuildVersionCodes.Kitkat)
{
PendingIntent pintent = PendingIntent.GetService(AppContext, 0, new Intent(AppContext, typeof(PushNotificationService)), 0);
AlarmManager alarm = (AlarmManager)AppContext.GetSystemService(Context.AlarmService);
alarm.Cancel(pintent);
}
}
我的pcl中的听众
public class CrossPushNotificationListener : IPushNotificationListener
{
public void OnMessage(JObject values, DeviceType deviceType)
{
Debug.WriteLine("Message Arrived");
}
public void OnRegistered(string token, DeviceType deviceType)
{
Debug.WriteLine(string.Format("Push Notification - Device Registered - Token : {0}", token));
}
public void OnUnregistered(DeviceType deviceType)
{
Debug.WriteLine("Push Notification - Device Unnregistered");
}
public void OnError(string message, DeviceType deviceType)
{
Debug.WriteLine(string.Format("Push notification error - {0}",message));
}
public bool ShouldShowNotification()
{
return true;
}
}
}
在app.cs(pcl)中注册(尝试LOL)
public App()
{
InitializeComponent();
CrossPushNotification.Current.Register();
MainPage = new NavigationPage(new Views.Splash2());
}
尝试注册后,我会遇到此错误。...(在Onerror方法中)

我想这不是您一直在寻找的确切答案,但是您,我和其他许多人都在使用此软件包。如果您不公开使用PushNotification,则应强烈考虑迁移。
